  • Biologists wrap up a day of sampling on Lake Mohave during the razorback sucker roundup, a multi-agency conservation effort that works towards recovering razorback sucker from the endangered species list.

  • Razorback sucker larvae, collected from various locations around Lake Mohave in order to retain the genetic divesity of the parental population, are reared in aquaria at Willow Beach National Fish Hatchery.  After a few months, the fish will be transfered to heated outdoor raceways where they will grow for three years before being repatriated into Lake Mohave.

  • A composite image of Yuma Cove backwater (right), one of few locations on Lake Mohave where razorback sucker recruitment occurrs annually.  The backwater is protected from an intruding fauna of predatory fish in the reservoir (left) by a narrow gravel beach.

  • A multi-agency group of biologist go over pre-flight instructions in preparation for flying the perimiter of Lake Mohave in search of spawning groups of razorback sucker.  The information is relayed to biologist on the water who will collect wild spawned larvae and transport tens of thousands of the small fish to Willow Beach National Fish Hatchery.

  • Shoreline of the lower basin on Lake Mohave where larval razorback suckers are collected each spring and then transported to a hatchery where they are raised for up to three years prior to being released back into the wild.

  • Biologists use underwater lights to attract, then capture endangered fish larvae along the shore of Lake Mohave.

  • Willow Beach National Fish Hatchery produces and stocks hundreds of thousands of nonnative rainbow trout into Black Canyon in Lake Mohave, most of which are consumed by striped bass.

  • Cold water released from Hoover Dam flows downstream through Black Canyon filling Lake Mohave.  Striped bass, which were incidentally introduced to Lake Mohave via the spillway tunnels of the dam during the 1980's, have been detrimental to the recovery of razorback sucker and other native fishes.

  • Lake Mohave is a narrow "run of the river" reservoir whose function is to ensure irrigation water reaches downstream reservoirs which supply the needs of farmers and cities in California and Arizona.  The reservoir also contains one of the largest and most genetically diverse populations of the endangered razorback sucker.

  • River water is pumped into cement raceways which house thousands of endangered razorback sucker at Willow Beach National Fish Hatchery. The rearing process includes treating fish with chemicals to ward off parasites and disease.

  • A biologist grills dinner over an evening campfire during a week of conducting population surveys of razorback sucker on Lake Mohave.

  • A campfire provides warmth on a cold winter evening during the third year of research on Lake Mohave.  The goal of the work was to determine how long aldult razorback sucker survive after being repatriated back into Lake Mohave.

  • Looking west across Cottonwood Basin, the widest portion of Lake Mohave, Arizona/Nevada.  The shoreline of the basin continues to provide wild spawned razorback sucker larvae, which supports recovery efforts of the species.
